Rope
Also known as “safety rope / ski rope”
The safety rope’s main function is to prevent any pipe separation which could result in the pump
being lost at the bottom of the well. Safety rope can also be a back up to enable the installer to
pull the pump from the well just in case the riser pipe fails or the connection gets separated.
It is recommended that every pump should have safety rope secured to the well head before
hanging it in the well. When selecting what rope you require, you should keep in mind the
weight of the pump, piping and wire.
The safety rope should be large enough to support the weight of the equipment. If you are using
galvanized pipe instead of poly pipe, you will need to take into factor that your rope will need to
be able to hold the extra weight.
